The valve unit 22 incorporates two similar valves 29, 30 each having a control element in the form of a tube 32 carrying a piston 31 which separates a chamber 33 communicating with a respective front axle spring 4, 5 from a chamber 34 communicating with the corresponding rear axle springs 7, 8 or 9, 10. Upward movement of a tube 32 lifts a valve disc 45 so that air from a receiver 27 charged by a compressor is supplied to the associated spring 4, 5, and downward movement of a tube 32 results in separation of the tube from the disc so that air is exhausted from the spring. The tubes 32 are jointly influenced in accordance with the front axle loading by a balance beam 37 linked to a lever 39 which is connected to the centre of the front axle 1 through a spring 41 and to the superstructure through a damper 42. The tubes 32 are also influenced by the pressure in the rear springs 7, 8, 9, 10 acting on the pistons 31 in opposition to that of the front springs 4, 5 so that the pressure differential between the front springs is the same as that between the rear springs and tilting of the superstructure is resisted by the springs on both axles.

Title: Piperazine adipate
Inventor: PETROW VLADIMIR
IPC: C07D295/027
Filed: 1954-05-28
Abstract: Piperazine adipate is prepared by reacting piperazine in admixture with substantial amounts of other nitrogenous bases with adipic acid and separating piperazine adipate in relatively pure form from the reaction product by elution with an unsubstituted aliphatic alcohol containing 1 to 5 carbon atoms, the adipates of the other nitrogenous bases being dissolved while piperazine adipate remains undissolved. The reaction between the piperazine containing nitrogenous base mixture and the adipic acid may be carried out in the alcohol and the piperazine adipate thereby precipitated directly therefrom. Alternatively the reaction may be carried out in aqueous medium with subsequent evaporation of the solution to dryness and elution with the alcohol.  Alcohols referred to are methanol, ethanol, industrial methylated spirit, n- and iso-propanol and n-butanol, Examples, including regeneration of piperazine from piperazine adipate by treatment of a slurry of the latter in acetone with potassium hydroxide solution, are given.  The Provisional Specification refers to the treatment of a piperazine containing fraction with the alcohol and adipic acid in any order and states that the piperazine content of the fraction may vary from below 5 per cent to almost 100 per cent.
